Specification of Letters Patent.

Application filed August 23, 1907. Serial No. 389,775.

To all whmri it may concern:

Be it known that 1, CHARLES H. MCCLIN- TOOK, a citizen of the UnitedStates, and a resident of Hartford Gity, Blackford county,

Indiana, have invented a new and useful Combined Carburcter and Governor for In ternal-Cornloustion Engines, of which the following is a specification.

This invention relates to improvements in carburetors for internal combustion engines.

Objects of my invention are to rovide a device of this character which wil be efiicient in operation, economical of manufacture, and not liable to get out of working order, and to afl'ord meanswhereby the supply of air and other fuel such as the hydro-carbone of crude oil will be automatically shut completely oii in case of the failure of the means by which the governor is driven.

The features of this invention consist of .the novel arrangement, construction and combination of parts herein shown, whereby the feeding of the oil and air which together constitute the fuel for the operation of the engine is accomplished in an improved man her, and whereby the amount of fuel consumed by the engine will be varied proportionally to the varying degree of ower 'de-' veloped by the engine, and where y in :case of breakage of the governor-belh'the valves of the oil-inlet and air-inlet will be automatically closed and retained in closed position.

My invention is shown arranged in opera tive position upon an internal-combustion to draw into-its mixing chamber-the admiie en ine-of well'known form of construction.

t will ,beunderstood that myinventiori may be applied to use on an engine of any sfsuitohle construction, and which is adapted ions, by suctionf tin-e ofairand-' eil -or otheriuel such as gasoi .Theio'bj ects of my -iuijthiandfoiher -pur case which will become 1B sclds d wefacoosepiished theineelissi imr uieamtsd m -the weierah e term of Tom.

} again secured by 24; the opst the collar 31 adjustably thjeset's'crew 32 to the said sha t posits end of the said coil-spring bein adaptthe of the valve-box is the head 36, against theunderside of which head bears the coilspring 37, .whereby the valve 34 is retained yieldingly infirm osition against its seat.

The head 38 of t e oil-inlet member is suitably bored so as to retain slidingly the plun er 39 and the upper end of thishead is perorated by .the small channel 40 where the pipe 41 leading from the oil Isupplyis secured. This small channel in turn commu v nicates with the enlarged oil passage 42 which extends aboutthe upper end' of the plun er and communicates with the oil inlet 13 W erebya free fiowof the oil entering the said channel is assured.

The plunger 39 is ta ered on its-end to fit in the cone-shaped en argement of the passage 42; its lower end has the shoulder 43 against which the end of the coil-sprin 44 having its opposite end against the is impinged. The stem 45 screwed into the end of the plunger 39 and adapted to be ad justably retained therein by the lock-nut 46, is provided with the foot 47 adapted to fit movably and freely in the camslot 48 of the regulator head 49, as plainly shown in Fi 5.

This regulator-head is adjustably secure on the shaft 24 by the set screw 50, and has'the ca'm-slot 48 provided therein to receive the foot 47 above referred to. Its opposite side is formed with a straight face so that there is ample clearance between it and the top of.

the head 36 when the latter is in its normal uppermost position. By this formation and arrangement of the parts the plunger will be retained with its foot 47 in engagement with the cam-slot 48 and the tapered end apart from the opening of the channel 40 and the width of this opening may be regulated to a nicety. Also such sli ht tendenc of the shaft 24 to revolve as t ere might e is thus overcome.

5O desi nates a sleeve adapted to fit loosely the end 0 the journal-box 16, the closed'end of this sleeve is bored to receive freely the shaft 18. The collar 51 rigidly secured to the shaft 18 is adapted to en age the closed end of the sleeve, as plainly shown in Fig. 5. Studs 52 rigidly secured on the sides of the journal-box enga e the diagonally disposed slots 53 in the s eeve. These slots are so formed with reference to the studs and to each otherthat when a rotary motion is imparted to the sleeve it will be forced against the collar 51 and the shaft 18 will be accord- 5 ingl shifted. Rigidly secured to and exten 'ng away from the sleeve 50, is the arm 54 disposed at a proper angle, upon its end which is disposed at a right angle is journaled the spool 55 ada ted to ride on the belt con- 6 necting the shat 11 of the engine and the pulley 19, as plainly shown in Fig. 1 and Fig.

3. The function of the weight 56 suitably secured on the arm 54, is" to actuate the sleeve 50. When the belting 57 connecting 35 the shaft 11 of the engine, and the pulley 19,

is. in position the spool 55 will rest on the belting and theweight 56 will be an ported. I From the foregoing disclosure of t e function and construction of the various arts of my invention, it will be easily un erstood that in the operation of the en ne the amount of oil and the amount of air esired to be fed may be regulated to answer any requirements and t0 the use of oils of va g density, and

91', that as the desired speed 0 the engine 1s attained the feed of the oil and air in the proportions asfixed, will be lessened or increased, as the performance of the engine is lesser or greater, as the case may be. A much desired result in-devices of the character herein described is a practical eans whereby the operation of the engine may be stopped in case of failure of the governor-belting. To accomplish this has been one of the main objects of this invention.

While I have shown my invention embodied in a mechanism of the construction described herein and-believe the best mode possible for thea plication of the principles 11r of the invention has been explained, it will be understood that minor changes may be made in the parts, and forms and details which will not in the least affect the nature or principles of my invention.

hen my improved combined carbureter and governor is installed in readiness for operation, it appears as shown in the drawings. As shown in Fig. 5 the lun er 39 and the valve 28, aFQsb &d]I1St6d t at t e tapered head of the plunger stands a art from the cone-shaped enlargement of t e assage 42, the valve 28 permits to be open tfie ports 33, and the valve 34 is closed. The spool 55 pests on the governor-belting as shown in rimultaneously with the starting of the engine, the valve of the oil' supply pipe is opened. As the carburization process progresses and the speed of the engine increases After these regulator-head 49.

i drops the sleeve tially as described.

in let leading I 50 ing a mixing chamber having a 5 5 pressed the consistency of'the mixture of oil and air, as the same reaches the valve 34, maybe I regulated to a nicety by the mani ulation of the adjustin lock-nut 46 and the ushing 26. ave been set as desired so that a certain feed of fuel for a given performance may be obtained, then the uota of the combined mixture roper to e .fed into the chamber, is fixe bythe adjustment of the The regulation of the speed of the engine is then automatically accomplished by he governor mechanism actuatm the regulator-head whereby the feed of t e mixed fuel is varied. In case of failure for any cause of the governor-belting then the weight56 is unsupported, and as it 50 is actuated whereby the plunger 39 and the valve 28 are instantly moved abnormally and the inlet of oil and air is completely shut oli, and the operation of the engine terminated. hat/ d claim as my mventlon, and desire to secure'by Letters Patent, isp '-1-.
